(Problem to be Solved by the Invention) As described above, in the conventional character reading system, in the processing routine of the reading processing program in the reading processing section, processing is executed by referring to FC information registered in advance. It had become.

By the way, when a property that requires individual processing for each user (user-individual property) occurs, the content of the reading process must be changed so that processing for the user-individual property is executed. Therefore, depending on the change in processing content, the FC generation program may
It was necessary to change both the read processing program and the read processing program. However, it is difficult for the user to change each program, and even if the manufacturer changes the specifications, it takes a lot of man-hours and effort to develop a processing system that corresponds to each user's individual property. There was a problem with it getting caught.

Executes processing according to the file name that specifies the program. The standard processing executed in the standard processing section 14 is executed based on the standard FC information stored in the standard FC information storage section 12. The user processing section I5 is activated via the interface section 1B when the file name stored in the standard processing table of the standard processing section 14 is a file name specifying a user program that performs user processing.

is executed based on the parameter information stored in .

Next, the operation of this embodiment will be explained.

The character reading system in this embodiment controls a character reading device to read characters written on a form. The form to be processed has a plurality of fields for specifying positions where characters are written. The character reading device includes a scanning mechanism unit that optically scans a form on which characters are written to detect a form image, and a recognition unit that cuts out a character pattern from the form image detected by the scanning mechanism unit and performs character recognition processing. It is composed of etc.

Also provided is a display section that displays character reading results and the like, and an input section that includes a keyboard and the like used by the user to input data into the character reading system.

First, a method of registering parameter information by the FC information creation section 11 will be described. FIG. 2 shows the configuration of a control sheet used in the character reading system of the same embodiment. In the first line of the control sheet, fields are provided for entering ID numbers, file names, etc., respectively.

From the second line onwards, fields for entering a plurality of parameter information are provided, and parameter information to be referred to when executing each process is entered.

The ID number is determined for each content of parameter information written on the control sheet, and it is determined whether the control sheet is for standard processing or user processing based on the ID number.

Registration of parameter information is performed according to the flowchart shown in FIG. First, one control sheet is taken out from a plurality of control sheets set up in a scanning mechanism (not shown) (step S1), and an image of the control sheet is detected. Next, a character recognition unit (not shown) reads characters indicating the ID number, file name, and parameter information written on the control sheet from the detected image. The FC information creation unit 11
Is the retrieved control sheet for standard processing?
Alternatively, it is determined based on the ID number whether it is for user processing (step S2).

If the control sheet is for the user, the file name entered in the file name entry field is retrieved (
Step S3). Here, a file for storing parameter information is created to store the parameter information written on the control sheet (step S4). Next, in step S4, the parameter information entered in the user control sheet is
The file name extracted in step S3 is stored in the file for storing the parameter information generated in step S5), and the file name extracted in step S3 is stored in the table for storing the file name (step S6). That is, the file name of the control sheet in which the common ID number is entered is stored in the file name storage table, and the parameter information corresponding to the file name stored in the table is stored in the parameter information storage file. . When the storage of the parameter information written on one control sheet is completed, it is determined whether or not the set-up control sheet has been completed (step S7), and if it has been completed, the registration of the parameter information is completed. If a control sheet remains, a new control sheet (one sheet) is taken out (step S1), and parameter information is set in the same manner. In addition, in step S2, if it is determined that the read control sheet is for standard processing, FC information used when performing standard processing is stored based on the parameter information entered in the standard control sheet. Table conversion processing for standard processing is performed (step S8). A detailed explanation of the table settings for standard processing will be omitted.

Here, the processing procedure of the standard processing section 14 will be explained with reference to the flowchart shown in FIG.

First, before starting the reading process, it is assumed that the job to be executed is selected, the reading mode is specified, etc. In the standard processing unit 14, in accordance with the selection of the specified job, a file name specifying a processing program to be executed by the character reading system is stored in a standard processing table (not shown) that is referred to when executing the standard processing. is set to When user processing is executed in response to this job selection, a user program file name specifying a user program is set in the standard processing table.

As for the reading mode here, an immediate correction mode is designated, and if a reject, a logical error, etc. exist, a request for correction is made at that point. In addition, the user process taken as an example here checks whether the character type of the character obtained as a recognition result is correct for the character entered in the field provided in the form targeted for character reading processing. shall be.

When the standard processing unit 14 is activated, it executes the standard processing specified by the program file name set in the standard processing table. First, the scanning mechanism section and character recognition section are instructed to execute processing, and character recognition processing is performed on the form to be processed. The standard processing section 14 extracts the recognition result for one field, J%, obtained by the character recognition process in the recognition processing section (step AI) and checks whether there is a reject character (step A2). If there are rejected characters, a request to correct the rejected data is output to the display unit (not shown),
For example, a reject pattern is displayed and the reject characters are corrected based on this (step A3). When the recognition result exists or the target data is corrected, for example, by manual input from the input section, a standard check (logical error check, etc.) on the recognition result is executed in the standard processing section 14. If it is determined through this standard check that error data exists, a request to correct the error data is output to the output section, and the error data is corrected (step A5).

Next, the standard processing unit 14 determines the processing to be executed in this processing stage based on the file name set in the standard processing table (step A6). If the process to be executed here is not a user process, the next process in the standard processing unit 14 is executed without starting the user process. On the other hand, if the file name of the user program is set in the standard processing table, the interface section 1B
creates an interface file 17 for transitioning from standard processing to user processing, which is referred to when executing user processing corresponding to the file name (step A7).
. The interface file 17 here is processed by the standard processing unit 14 because the user processing is processing to check whether the recognition result for characters entered in one field is correct. Various field information necessary for executing user processing is set, such as information specifying a field and information specifying a file in which recognition results for the field specified by this information are stored. Furthermore, the file name of a file in which parameter information defining user processing is registered is set in the interface file 17. That is, a file name designating parameter information stored in the parameter information storage table of the user FC information storage section 13 is set.

When the interface file 17 for transitioning to user processing is thus created in the interface section 1B, the user processing program in the user processing section 15 is started (step A8). User processing unit 15
executes user processing while referring to the interface file 17 generated in the interface unit 16 (step A9). That is, the user processing unit 1
5 reads parameter information from the parameter information storage table of the user processing FC information storage section 13 based on the file name of the file in which the user parameter information set in the interface file 17 is stored;
User processing is executed based on this parameter information.

The parameter information here is set with information (information specifying the character type, etc.) for checking the character type for the recognition result of one field, which is necessary to execute the user process. When the user processing is completed, the user processing unit 15 sets a return status according to the processing result of the user processing. In other words, the return status is set depending on whether the data indicating the recognition processing result is determined to be correct (correct data) or incorrect (error data) by character type check (user processing) for one field. Set.

Here, the interface unit IB determines the processing result of the user processing based on the return status (step A10). When the recognition processing result is determined to be error data based on the return status, the interface unit 1B generates an interface file 17 that is referred to when the standard processing unit 14 executes processing for correcting the recognition processing data (step A11). This interface file 17 includes, for example, information regarding the file in which the recognition processing data is stored, an error message instructing to correct the recognition result, information regarding the handling of the recognition processing data (here, data display is specified), and Information specifying key protection processing when modifying recognition results is set. Note that the information specifying the protect process specifies a key that can be used when correcting the recognition process data by inputting correct data manually.

For example, if the user processing in the user processing unit 15 determines that it is error data because a character that should exist in one field to be processed is a numeric character instead of an alphabetic character, a key that can be used when correcting the error is detected. is specified as an alphabetic key. When the interface file 17 for performing the error data correction process is generated, the error data correction process in the standard processing section 14 is activated. The error data correction process is executed based on the contents of the interface file 17. first,
The recognition result data determined to be error data and the error message set in the interface file 17 are displayed on the display section, and the user is requested to correct the error data (step A12). When the user inputs correct data based on the displayed error data and error message, the data in the file storing the recognition processing data is corrected.

Thereafter, user processing is performed again on the recognition result data of one field to be processed that has been corrected. This processing procedure is the same as the procedure explained above, so it will be omitted here.

On the other hand, if the recognition processing result to be processed by the user processing is determined to be correct (correct data) according to the return status (step 5IO), the interface unit 1B executes the next standard processing in the standard processing unit I4. An interface file 17 is generated to be referenced when performing the process (step A14). When this interface file 17 is created, standard processing in the standard processing section 14 is started and the next processing is executed.

In the above embodiment, the user processing executed in the user processing section 15 is to check whether the recognition result of the character written in one field is the correct character type. The content and the specific processing step of transitioning from standard processing to user processing can be set arbitrarily. For example, the user processing unit 15 performs processing such as checking each document that is subject to character reading processing, editing the character reading results on a field-by-field or document-by-form basis, and displaying the result in a user-specific display format. The user process set in is executed. In addition, since the parameter information written on the control sheet is set in the user FC information storage unit 13 according to the user processing set in the user processing unit 15, the handling of the parameter information is also handled by the user processing in the user processing unit 15. It can be set arbitrarily by

In this way, by providing the user processing section 15 that can arbitrarily set the processing content to correspond to the user's individual property, and the standard processing section 14 that is executed regardless of the user processing, it is possible to perform processing other than the standard processing. Things can be operated to suit individual users. Further, since standard processing only requires basic processing, the content of standard processing is not complicated, and development man-hours and efforts are limited. Furthermore, since the information defining the user processing to be executed in the user processing section 15 is in a parameter format, even if the specifications need to be changed, they can be easily done.

[Effects of the Invention] As described above, according to the present invention, in a character reading system that performs reading processing of characters written on a form, a standard processing section that performs standard processing and a user processing section that performs processing with a specific purpose are integrated. The user processing section sets read control information for user processing used in the user processing section as a parameter, and the user processing section performs processing for user-specific properties that require user-specific processing.
Even if it is necessary to change the processing content according to the user's individual property, there is no need to change the standard processing unit. Therefore, it becomes possible to easily deal with the user's individual properties.
